That sounds like my setup in the buggy- open induction, free-flow exhaust, but stock manifolds.

What are the characteristics of this cam, i.e., "It's a little softer to about 2000rpm, and then picks up and pulls stronger to redline"

Also, since I'm a relative LSx nOOb.. are new springs (918's seem to be the crowd favorite?) & pushrods required/recommended?

Thanks!
